Vargus 50272 Threading Insert 48-16 Tpi Solid Carbide

Product Description

The VARGUS 50272 is a solid carbide laydown threading insert designed for right-hand internal thread cutting at a 60-degree partial profile. The insert carries a TiAlN finish applied via PVD coating, which provides thermal resistance and extended tool life across a broad range of workpiece materials. It is rated for 48 to 16 TPI and covers a metric pitch range of 0.50 to 1.50 mm. With a 6.35 mm (1/4 inch) inscribed circle and a thickness of 3.17 mm, this insert seats in standard 2IR-style toolholders. It is installed by machinists and CNC operators in turning and boring operations requiring precise internal thread profiles.

This insert is suited for internal threading applications in both production and job-shop environments. The 60-degree partial profile geometry accommodates unified and metric thread standards within the covered pitch range. The universal primary workpiece material rating makes it applicable across steel, stainless, cast iron, nonferrous alloys, and high-temperature alloys, corresponding to ISO material groups H, K, M, N, P, and S. It is a standard-series insert intended for CNC lathes and manual turret lathes equipped with compatible 2IR boring bar holders.

Key Features

• Solid carbide substrate with PVD-applied TiAlN coating for thermal and wear resistance
• Right-hand internal threading, 60-degree partial profile geometry
• Covers 48 to 16 TPI and 0.50 to 1.50 mm pitch range in a single insert

• Universal material compatibility across ISO groups H, K, M, N, P, and S
• Manufactured to ISO 9001:2008 quality standards

Compatibility

Designed for use in 2IR-style internal threading toolholders. Confirm holder bore clearance and minimum bore diameter requirements against the 6.35 mm inscribed circle before installation.

Installation Notes

Installation is performed by machinists following standard CNC or manual lathe tooling procedures. Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or clamping key specified for the toolholder to secure the insert without overtightening. Verify insert orientation and hand designation match the toolholder and programmed thread direction before resuming cuts.
